How to Check if a Vehicle Has Taken in Water?
2 Answers
Open the air intake filter housing, as water entering the intake side must pass through here, and check if the air filter mesh is damp. Remove the vehicle's spark plugs and use a flashlight to inspect the condition of the spark plug tips to determine if water has entered. If water has entered the oil chamber, the head of the dipstick will show abnormalities and differ in color from the engine oil. If the engine oil turns milky white, it indicates that water has entered the fuel tank or engine. Inspect the lower housing of the air filter for any signs of water entry one by one, and check the intake pipe and intake manifold for traces of water.
My car once got flooded, and I was really panicked at the time. After the rain, I went to the garage, and as soon as I opened the door, I smelled a musty odor, like wet clothes left for too long—this is usually the first sign. I crouched down and felt under the floor mats; some spots were damp with mud stains, clearly from rainwater seeping in. Then I checked the door frames and the edges of the trunk, where small puddles tend to accumulate—running my fingers over them, I could feel the slippery moisture. Next, I popped the hood to inspect around the battery and wiring—if water gets in, it can corrode parts, causing flickering lights or starting issues. Oh, and don’t forget to check the spare tire well in the trunk; it’s deep and easy to overlook if water gets in. Act fast: soak up water with dry cloths and ventilate by opening windows to prevent mold and interior damage. Finally, take it to a repair shop for a professional safety check with tools. Flood-damaged cars have hidden risks—affecting health and driving—so don’t delay!
